The best advice I can give is focus on your content. Make sure you're creating content people want to watch. That's why some here suggested researching your genre and the people searching for your type of content and what's trending. Work on improving your videos by learning new ideas, tips and tricks that can make them look and sound better, seem more appealing to new viewers and help them stand out in a crowded genre. Don't be afraid to try new things to see what works and what doesn't. Change what doesn't work, keep what does and improve upon it. Let your channel grow naturally. If you place too much focus on your numbers you can find yourself disappointed because channels don't always grow overnight, it takes time, and these disappointments could have negative effects on how you create content. Work on creating good content ppl want to watch and/or listen to. The analytics can come later.
but I'm a visual person, so my tips always relate around visual first impressions. People click thumbnails to watch a video, so the visual of the book cover is important, even if they say "never judge a book by it's cover"
